STANDARD WELDED STEEL BAR GRATING
15W4 & 15W2 15/16" CENTER TO CENTER OF BEARING BARS

Welded Steel Bar Grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Universally used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.

It is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring. More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness. And, where insurance codes permit, additional sprinklers can often be eliminated. Standard panels are available in widths of 2', 3' or 4'.



Welded steel bar grating is resistance welded to create a rugged, one-piece constructed panel. The bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint. The cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.



All panels listed are 3 ft. wide x either 20 ft. or 24 ft. long. Panels are painted black; one end is untrimmed.

Add $0.63 sq. ft. for serrated panels (3/4 x 1/8 not available serrated)

Add $0.63 sq. ft. for 2 ft. wide panels
Add $0.63 sq. ft. for 2 ft. wide panels

MINIMUM ORDER OF ONE PANEL - LESS THAN ONE PANEL: ADD $124.83 CUTTING CHARGE

U = safe uniform load, psf		Material: ASTM A-569 standard
C = safe concentrated load, pfw		Deflection: Spans and loads to the right of the bold line exceed 1/4" deflection for uniform load of 100 psf which provides safe pedestrian comfort. These can be exceeded for other types of loads with engineer’s approval.
D = deflection, inches
E = modulus of elasticity, 29,000,00 psi
F = fiber stress, 18,000 psi
		Serrated Bars: For serrated grating, the depth of grating required for a specified load is 1/4" deeper than that shown in the table.
		General: Loads and deflections are theoretical and based on static loading.
